Hva betyr feilkoden?
The upper electronic module (UEM) feeds several functions through the extended X supply (EXT X): the sun roof logic, the sun visor mirror lamps, the rain sensor, and the buttons for the roof lighting along with some button lighting. The code is set when the feed to these functions is too low, because it is shorted to ground. Several functions then stop working.
Mulige årsaker
- The feed to the sun roof, the sun visor mirror lamps, the rain sensor, the roof lighting buttons and some button lighting is short-circuited to ground
Hva du kan gjøre
- 1Check that the fuses for the sun roof and the interior lighting are intact.
- 2If all of these functions stop working at the same time, the cable from the upper electronic module to the junction point, or the wiring from there, may be shorted to ground.
- 3Use a multimeter to check that the wires have no contact with ground (the bodywork).
- 4Check that the rain sensor wire is not pinched under the foot of the interior rear view mirror, and unplug its connector to inspect it separately.
- 5If the fault remains, have a workshop check the wiring.
